New research shows that testosterone may foster social behavior and honest interactions.
Researchers gave 46 people testosterone gel and 45 people a placebo.
The next day, all 91 people were invited to roll the dice in private, report the numbers they landed on, and receive money based on their results—with the higher rollers netting more cash.
After paying out the participants, the researchers found that men who received the testosterone gel self-reported their numbers more honestly.
